| Summary: | The title compound, C18H8Cl4N4, exists in a cis configuration with respect to the bridging C=C bond. The two essentially planar quinoxaline ring systems [maximum deviations = 0.012 (1) and 0.022 (1) Å] are inclined at an angle of 59.84 (3). In the crystal, adjacent molecules are linked into chains propagating along [001] via intermolecular C—H...N hydrogen bonds. Weak intermolecular π–π [centroid–centroid distance = 3.6029 (7)°] and C—H...π interactions are also observed. |
